Yes, you can spend the $1.50 savings on unemployment for the people that are now out of work. That's is so much better. And since Probably $1.70 of the original $2 price was labor, government income tax revenues just fell $0.34. So now after you've paid for their unemployment, you can higher taxes to make up for the government shortfall. That's so much better!!!!
You assume a static model that has only so much pie.
Wealth comes from making more pie. Not by how you divide some fixed amount of pie.
